*CDI, Clostridium difficile infection.†Categories determined by panel review. Because panel review was considered the reference standard, panel review percentages = 100%.‡Because recurrent CDI is not always supported by laboratory or pathology confirmation, those patients with recurrent symptoms suggestive of CDI but no toxin confirmation were included by using the date of clinical onset of symptoms nearest to the date of death.
